AI-Powered KYC Fraud Detection

We embedded an intelligent fraud detection layer into an existing KYC platform — combining real-time face recognition, liveness detection, behavioral signals, and a multi-dimensional feature store to block fraudulent verifications before they reach compliance teams.

The Challenge

The client's KYC platform was processing thousands of verifications daily but lacked the intelligence to catch sophisticated fraud attempts — including printed photo spoofing, video replay attacks, deepfakes, and identity theft through stolen selfies. Manual review could not scale, and false negatives were reaching onboarding downstream.

What We Built

We designed and integrated a Python-based AI microservice into the existing KYC flow via REST APIs and micro frontend techniques. A React component library rendered the liveness capture UI within the host app without requiring a rewrite of existing screens. The AI layer ran on a dedicated inference cluster and communicated asynchronously, keeping the KYC flow non-blocking and audit-ready.

Face Recognition & Liveness Detection

  • Real-time face embedding matching against registered identity using vector similarity search (Pinecone / Qdrant)
  • 3D liveness detection — distinguishes a live human face from a printed photo held to the camera
  • Video replay & screen-capture attack detection — flags pre-recorded video played in front of a webcam
  • Deepfake confidence scoring using texture inconsistency and micro-expression analysis
  • Automatic KYC halt with reason code when fraud confidence exceeds threshold

Multi-Signal Fraud Detection (Feature Store)

  • IP reputation check — blocks requests originating from blacklisted IPs, known VPNs, Tor exit nodes, and datacenter ranges
  • Geo-location gating — rejects KYC attempts from sanctioned countries and high-risk jurisdictions
  • Device fingerprint velocity — flags the same device submitting multiple unique identity applications in a short window
  • Session anomaly scoring — unusual time-of-day patterns, bot-like interaction speed, or clipboard-paste activity on ID fields
  • Document tampering detection — ML classifier on uploaded ID images to detect font inconsistencies, edge artifacts, and metadata manipulation
  • Cross-customer deduplication — vector DB lookup to surface faces or documents already linked to a flagged or banned account

Integration & Architecture

The AI service was shipped as a Python FastAPI microservice — stateless, horizontally scalable, and containerized. The React liveness-capture module was embedded into the client's existing app as a micro frontend via Module Federation, requiring zero changes to the host app's router or auth layer. Face embeddings and fraud signals were stored in a vector database (Redis) enabling sub-10ms similarity lookups at scale. A structured audit log captured every decision with confidence scores for compliance reporting.

TravelTech AI Feature · RAG · Agentic

Agentic RAG Travel Chatbot

We embedded a production-grade agentic chatbot into an existing travel agency application — combining Retrieval-Augmented Generation, semantic routing, live inventory queries, and intelligent human handoff to deliver instant, accurate answers while keeping LLM costs under control at scale.

The Challenge

The client's support team was drowning in repetitive queries — seat availability, hotel room inventory, booking status, and generic FAQs — all being handled manually. Response times were high, after-hours coverage was non-existent, and LLM prototyping attempts had resulted in hallucinations and uncontrolled API costs. They needed an intelligent assistant that was accurate, cost-conscious, and could hand off gracefully to a human agent when needed.

What We Built

We delivered a RAG-based agentic chatbot integrated directly into the client's existing React application via a lightweight SDK drop-in — no rebuild required. The agent is backed by a Python / LangGraph orchestration layer that handles intent detection, model routing, tool calls via MCP servers, and a Redis-powered infrastructure stack handling caching, vector search, guardrails, and semantic deduplication — all running on Kubernetes for elastic scaling under peak travel seasons.

Live Data Retrieval via MCP & RAG

  • Real-time seat availability queries for buses, trains, and flights — pulled live from the booking DBs via MCP server tool calls
  • Hotel room inventory lookup across multiple properties with date-range filtering
  • Customer booking details — PNR lookup, itinerary summary, cancellation status
  • FAQ answering via RAG — policy documents, refund rules, baggage allowances chunked and stored as vector embeddings in Redis
  • MCP server layer abstracts all DB connections — chatbot never queries SQL directly, ensuring clean separation and auditability

Semantic Routing & Agentic Logic

  • Semantic cache (Redis) — semantically similar queries reuse prior responses, cutting LLM token spend significantly for repeat question patterns
  • Intent-based model routing — lightweight queries handled by a fast, cheap model; complex reasoning escalated to a capable model automatically
  • Conversation re-engagement router — detects when a user goes silent or pivots and pulls them back with a contextual follow-up
  • Human agent handoff — routes to live support when confidence is low, sentiment is negative, or the user explicitly requests a human
  • Guardrails layer (Redis-backed) — blocks off-topic prompts, PII leakage, jailbreak attempts, and out-of-scope travel queries before they hit the LLM

Infrastructure & Scalability

The entire stack — orchestration layer, MCP servers, embedding pipeline, and guardrail service — runs on Kubernetes with horizontal pod autoscaling, handling traffic spikes during peak booking seasons without manual intervention. Redis serves as the single AI infrastructure backbone: vector store for RAG embeddings, semantic cache for LLM response reuse, guardrail rule store, and model routing decision cache. All agent steps are logged with full trace context for debugging, cost attribution, and compliance audit.

FinTech End-to-End Platform

FEXP — Financial Services Marketplace

A comprehensive fintech ecosystem enabling end users to discover, compare, and apply for financial products — credit cards, personal loans, CIBIL score improvement, and more — all from a single, beautifully designed platform.

The Challenge

The client needed a consumer-facing financial services marketplace where users could explore and apply for various financial products. The platform had to be fast, mobile-friendly, and capable of handling sensitive financial data with compliance-grade security.
